    Changes in perceived travel cost and time for the work trip during a period of increasing gasoline costs (1981)

    Notes: Abstract This study was designed to examine the relationship between actual and perceived values of cost and time for the work trip and to examine how perceptions have changed over a period of dramatically increased travel costs. Variations in the relationship between perceived and actual values were examined as a function of situational and attitudinal variables. Two telephone surveys were conducted one year apart (Fall 1978 and Fall 1979). On the next working day following a survey, a research assistant recreated the respondent's work trip, recorded time values and used distance measures, car type information and parking costs to compute travel cost. The first survey revealed that most auto users were unable to articulate dollars-and-cents driving costs for the work trip, but auto users in the second survey were able to provide fairly accurate cost estimates. Dramatic changes in fuel prices between surveys is probably the main reason for the change in driving cost awareness. Auto users were also asked to rate relative costs of driving a car compared to using the bus for the work trip. These ratings showed that auto users tended to underestimate driving costs relative to bus costs, but this tendency decreased from the first to the second time period. Commuters in all modal groups at both time periods tended to overestimate travel times. Perception of travel time varied as a function of mode, perceived comfort (for car users), and perceived convenience and number of transfers (for bus users).

    Gene flow among population of a teleost (painted greenling, Oxylebius pictus) from Puget Sound to southern California (1981)

    Notes: Abstract Four geographic populations of the painted greenling Oxylebius pictus, a small cryptic reef fish of the western coast of North America, were examined for biochemical evidence of genetic differentiation. Painted greenlings in Puget Sound and those in central and southern California are similar by Nei's genetic identity (I=0.966 to 0.995); Fowever, other observations argue for genetic differentiation among the 4 populations. First, there are geographic differences in allelic frequencies at two loci (Est-3 and Pgm), with a geographic cline exhibited at the latter locus. Second, and most significant, two assayable loci are uniquely present in pairs of populations below Point Conception (G3pdh-3) and above Point Conception (Idh-3), respectively. Larval dispersal patterns are inferred from breeding times for the painted greenling and on patterns of currents off the western coast of North America. We believe that gene flow in this species is less across Point Conception than between Puget Sound, Washington, and Monterey, California, on the basis of these genetic data and the patterns of dispersal.

    Dependence of dissolved carbohydrate concentrations upon small scale nanoplankton and bacterioplankton distributions in the western Sargasso Sea (1981)
    Springer
    Marine biology 65 (1981), S. 289-296 
    Details

    Topics: Biology
    Notes: Abstract Significant correlations between trophic components of the 〈20 μm microbial plankton and the concentrations of total dissolved carbohydrate (TCHO) and polysaccharide (PCHO) have been found at two drogued buoy stations which were sampled at 3 or 4-h intervals over diel cycles. An attempt was made to sample on two pre-selected isotherms (approximating isopycnals) at each station. Significant inverse correlations of TCHO and of PCHO with numbers of phototrophic nanoplankton (PNAN) were found along both isotherms at a station off the Carolina coast. Off central Florida, TCHO and/or PCHO were significant multiple linear functions of PNAN, heterotrophic bacterioplankton (BAC) and sometimes heterotrophic nanoplankton (HNAN) counts. Partial regression coefficients for PNAN were always negative and those for HNAN were positive. Inverse trends dominated the relations of BAC with PCHO and TCHO. The combined data from the two stations (300 nautical miles apart) produced very similar multiple linear relations. This suggests that the observed relationships are real, resulting from general physiological processes and interactions of the microbial plankton groups rather than from chance occurrences at a particular station, and that the combined activities of the 〈20 μm plankton actively regulate dissolved carbohydrate concentrations in the Sargasso Sea.

    The effect of pollinators, predators, and energy constraints on the floral ecology and evolution of Trillium erectum (1981)
    Springer
    Oecologia 48 (1981), S. 400-406

    Topics: Biology
    Notes: Summary The reproductive success and energy budgets of single and multiflowered plants of Trillium erectum L. (Liliaceae) were assessed over a period of 4 years. Plants with more than one flower were found to attract more pollinators, to be less vulnerble to predation by Tortricid moths, and to produce more seeds than single flowered plants. Despite the reproductive superiority exhibited by multiflowered plants, most plants (85%) in the population studied were single flowered. It is shown that even though the insect interactions make it advantageous to produce more than one flower, most plants lack the energy to do so. The optimality approach which has guided previous studies of this kind is criticzied.

    Toxigenicity of fungi from grain sorghum (1981)
    Springer
    Mycopathologia 75 (1981), S. 23-26 
    Details
    ISSN: 1573-0832
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract The mycoflora of nine varieties of grain sorghum was determined by plating serial dilutions of ground samples on rose bengal-streptomycin agar. Seventeen species of fungi representing 10 genera were identified. Curvularia, Penicillium, Mucor, and Aspergillus were dominant genera. Extracts of P. herquei were highly toxic to brine shrimp, while those of C. clavata, C. lunata, and Mucor mucedo showed low to moderate toxicity. Extracts of C. clavata, C. lunata, and M. mucedo were highly toxic to chicken embryos; those of six other species showed low to moderate toxicity. Extracts of C. clavata, C. lunata, M. mucedo, Fusarium moniliforme, Alternaria tenuissima, P. herquei, and P. steckii showed varying degrees of toxicity to day-old cockerels.

    Gradient theory of fluid microstructures (1981)
    Springer
    Journal of statistical physics 24 (1981), S. 243-268 
    Details
    ISSN: 1572-9613
    Keywords: Fluid microstructures ; thin films ; periodic fluid microstructures ; statistical mechanics of inhomogeneous fluids ; disjoining pressure
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The general gradient theory of fluid microstructures is outlined. This theory reduces the determination of fluid microstructures to a boundary value problem. The density and pressure tensor profiles and the tension of planar thin films and layered structures in one-component fluids are investigated. The boundary conditions determining these structures are given a geometric interpretation in the free energy-density diagram. Discussed are the implications of the theory for the validity of Antonov's rule, the duplex film hypothesis, and the asymptotic theory of disjoining pressure and of the origin of a characteristic length scale in spinodal decomposition.
